Description
Technical field
The present invention relates to technical fields of mechanical processing, the especially technical field of turnery processing screw thread.
Background technology
When turnery processing screw thread, ideally, there are more than 0.1mm~0.2mm for the crest diameter polished rod size of preceding process
Amount, using the full tooth form screw thread process of standard, when finishing screw thread, as shown in Figure 1, threaded blade（See Fig. 2）Two cutting edge a and
B can participate in cutting, it can cut the entire form of thread including crest, and cutting edge a is ensureing form of thread just
Really, cutting edge b ensures the correct of screw thread tooth top.
But due to soft aluminium（Such as LF21R/LF21）Material property, good-extensibility, plasticity_resistant deformation ability is poor,
And processing medium temperature spends height, easily occurs being stained with knife, forms built-up edge in point of a knife, causes the rotten tooth of screw thread as shown in Figure 3, Figure 4.
Invention content
To solve the above-mentioned problems, the present invention provides a kind of method solving the soft aluminium accessory turning processing rotten tooth of screw thread, easily
It in realization, and can guarantee the processing quality and dimensional accuracy of workpiece, improve production efficiency.
Technical solution of the present invention is：
A kind of method of the soft aluminium part screw thread of turnery processing of the present invention, includes the following steps：
S1：Select coolant liquid：Select the stronger coolant liquid of viscosity；
S2：Select blade：The threaded blade of big 1 grade of screw pitch is selected to substitute the threaded blade for needing normal process screw pitch;
S3：Using lateral feed mode, blade is processed with being fed less than the angle of thread of relief angle；
S4：Select cutting parameter：Screw thread single cycle back engagement of the cutting edge ap=0.05mm~0.07mm, linear velocity Vc=55~60rpm.
In the step S3, processing screw chasing programming mode is：Using the cutting recursion instruction processing of G76 multiple whorls
Screw thread.
The stronger coolant liquid of viscosity be De Luke Denucool SM8400 water solubility cuttings liquids, a concentration of 15%.
The top diameter polished rod size of the soft aluminium part screw thread is processing screw thread process in place, not made allowance.
The present invention has the beneficial effect that：
By reasonably selecting coolant liquid, blade, programming mode, cutting parameter, optimize the entire of the soft aluminium part screw thread of turnery processing
Manufacturing process system solves the problems, such as the soft aluminium part processing rotten tooth of screw thread, ensure that product quality, can be machined
Etc. industries quickly popularize in an all-round way.

Wherein：1 it is screw thread, 2 be threaded blade, 21 be main cutting edge, 22 is tooth top cutting edge.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
A kind of method of the soft aluminium part screw thread of turnery processing of the present invention, includes the following steps：
The first step：Select coolant liquid：Select the stronger coolant liquid of viscosity；
Second step：Select blade：The threaded blade 2 of big level-one screw pitch is selected to substitute the threaded blade 2 for needing normal process screw pitch;
Third walks：Select screw chasing programming mode：Using G76（Multiple whorl cuts recursion instruction）Screw thread is processed, is used
The lateral feed mode of G76 programmings, as shown in figure 5, blade less than the angle of thread of relief angle to feed
4th step：Select cutting parameter：Screw thread single cycle back engagement of the cutting edge ap=0.05mm~0.07mm, linear velocity Vc=55~
60rpm。
By taking the screw thread process of part M10 × 1.5-6h as an example：
The first step：Reasonably select coolant liquid：The stronger coolant liquid of viscosity is selected, process is fully cooled, preferably moral
The Denucool SM8400 water solubility cuttings liquids of Luke, a concentration of 15%；
Second step：Select rational blade：The threaded blade 2 of big level-one screw pitch is selected to substitute the screwer for needing normal process screw pitch
Piece, such as the alternative threaded blade ISO1.5 (pitch P=1.5) of threaded blade ISO1.75 (pitch P=1. 75)；
Third walks：Select screw chasing programming mode：Using G76（Multiple whorl cuts recursion instruction）Screw thread is processed, is used
The lateral feed mode of G76 programmings, as shown in figure 5, blade less than the angle of thread of relief angle to feed
4th step：Select cutting parameter：Screw thread single cycle back engagement of the cutting edge ap=0.05mm~0.07mm, linear velocity Vc=55~
60rpm。
When processing soft aluminium part screw thread 1, the top diameter polished rod size of screw thread 1 is ensured by preceding process turning, not made allowance, then is selected
Being substituted with the threaded blade 2 of big level-one screw pitch needs the threaded blade of normal process screw pitch, as shown in Figure 5, Figure 6, threaded blade master
Cutting edge 3 and screw thread tooth top also have certain gap, when processing form of thread will not screw cutting tooth top simultaneously, can effectively avoid
Screw thread tooth top crossed cut because part is plastically deformed, will not caused by point of a knife built-up edge the rotten tooth of screw thread, tooth top cutting edge 22 is most
Ensure screw thread tooth top size afterwards.
Select screw chasing programming mode：Using G76（Multiple whorl cuts recursion instruction）Process screw thread；
Using G76 program lateral feed mode, as shown in Figure 7, Figure 8, threaded blade 2 with less than the angle of thread of relief angle feed,
Chip control performance is fine, and generated heat is small on point of a knife, also, can effectively reduce vibration using lateral feed, ensures zero
Part machined surface quality.
